ROTARY PUMP OR COMPRESSOR.

Specification of Letters Patent.

Patented Jan. 17, 1911.

Application filed December 23, 1909. Serial No. 534,730.

To all whom it may concern:

Be it known that we, ROBERT M. SLOAN and ZAoi-mnr M. LINDLEY, citizensof the United States, residing at Carthage, in the county of Jasper andState of Missouri, have invented a new and useful Rotary Pump orCompressor', of which the following is a specification.

The invention relates to a rotary pump or compressor.

rlhe object of the present invention is to improve the construction ofrotary pumps, and to provide a pump structure, designed for pumping oilor water, compressing air and analogous operations, and equipped with acontinuously rotating head, carrying a reciprocatory piston or plunger,movable transversely of the rotating head to take in the material at theinlet port and dis charge the same at the outlet port, and operated bymechanism capable of reciprocating the piston or plunger, while the sameis at or opposite the inlet or outlet ports, and of also holding thepiston or plunger stationary with respect to the rotating head while theformer is traveling between the inlet and outlet ports.

Another object of the invention is to equip the pump with means forstoring power during the periods when the piston or plunger is travelingbetween the inlet and outlet ports and for expending the same to assistthe engine or other motive power for actuating the pump, whereby thecapacity of the engine necessary to operate the pump is reducedpractically one half.

rlhe invention also has for its object to provide means for maintainingthe necessary liquid or air tight fit or connection between the rotatinghead and its casing, and to provide adjustable means for the piston orplunger, adapted to maintain a liquid and air tight lit between thepiston or plunger and the head and to preserve the proper Vrelationbetween the ends of the piston or plunger and thev outer casing, whilethe former is traveling between the inlet and outlet ports, so that afull charge of material operated on will be carried from the inlet tothe outlet port and completely discharged at the latter withoutreturning any of the liquid to the inletport.

With these and other objects in view, the

invention consists in the construction and novel combination of partshereinafter fully described, illustrated in the accompanying drawings,and pointed out in the claims hereto appended; it being understood thatvarious changes in the form, proportion, size and minor details ofconstruction, within the scope of the claims, may be resorted to withoutdeparting from the spirit or sacricing any of the advantages of theinvention.

In the drawings Figure 1 is an elevation of a rotary pump or compressor,constructed in accordance with this invention. Fig. 2 is a centrallongitudinal sectional view of the same. Fig. 3 is a transversesectional view. Fig. 4 is a plan view, the outlet or discharge pipebeing in section. Fig. 5 is a horizontal sectional view on the line 5-5of Fig. 2. Figs. 6 and 7 are diagrammatic views, illustrating theoperation of the reciprocatory piston or plunger and the actuating meanstherefor. Fig. 8 is a detail sectional view, illustrating theconstruction of the cushioning devices.

Like numerals of reference designate corresponding parts in all theligures of the drawings.

In the embodiment of the invention, the continuously rotating head 1 isin the form of a ball or sphere, operating withinv a substantiallyspherical outer casing 2, composed of a series of horizontally placedsections and interposed packing rings 3, which, when the sections aredrawn together, are compressed and forced inwardly, whereby a liquid andair tight fit or connection is maintained between the outer casing andthe ball. The top and bottom sections 4 and 5 are provided withapproximately segmental enlargements, forming outlet and inlet chambersor cavities 6 and 7, which are approximately segmental, as clearlyillustrated in Fig. 3 of the drawings. The bottom section is of a sizeto receive slightly less than half of the head. OThe intermediatesections 8 and 9, which are located centrally of the head, arepreferably of uniform size and the intermediate section 10, which isinterposed between the section 8 and the top section, is slightlynarrower than the said sections 8 and 9. The circular or ring-shapedsections, however, may be of any desired number, and the packing rings,which commencel slightly below the center of the ball, are arranged atintervals between the lo-wer packing ring and the upper chamber 6 inorder that the rotary head may carry a full charge of material from thebottom of the casing to the outlet chamber and to prevent therotary'head from carrying any of the liquid backward from the outletchamber 6 to the inlet chamber or cavity 7.

The sections of the outer casing are provided withhorizontallyprojecting arms 11, disposed diametrically of the pump andradiating from the spherical casing, as clearly shown in Fig. 5 of thedrawings. The arms 11 of the sections of the outer casing are arrangedin vertical series and are supported by vertical standards 12 o-f a baseplate 13. The packing rings are also provided with extensions 14, whichare fitted between the arms 11, and the latter are connected with thestandards 12 by vertical screws 15, piercing the arms and the extendedportions of the packing rings and engaging threaded openings or sockets16 of the standards. The lowerl ends of the screws may be fixed oranchored to the standards in any other desired manner, and the upperends of the screws are provided with nuts 17, adapted to be rotated forcompressing the packing rings. Any other suitable means, however, may beemployed for compressing the packing rings and securing the sections ofthe outer casing together. The standards or pedestals 12, form rigidsupports for the casing at each corner of the base plate, and the ump isthereby rigidly held in position on tile said base plate.

The casing is provided at the bottom with an inlet port 18, which may beconnected by a pipe 19, or other suitable means with the source ofsupply, the pump being adapted for raising water or oil and may beadvantageously employed in the oil fields for pumping the oil to therefineries. The top of the casing, which is provided with an outlet port20, has a discharge or outlet pipe 21 connected with it, and the casingis also equipped with an air dome 22, arranged at the top of the casingand communicating with the discharge chamber or cavity.

The rotary head is provided with a cylindrical diametrically arrangedopening 23 in which a reciprocatory piston or plunger 24 operates. Thereciprocatory piston or plunger, which is circular in cross section, isprovided lat its ends with adjustable end members or sections 25, alsocircular in cross section and having' a rounded or convex outer end face26 to lit the interior bearing surface of the outer casing. The-outerend faces of the adjustable end sections or members 25 conform to theconfiguration of the outer cylinder and accurately fit the same, so thatwhen one end of the piston is traveling from the outlet chamber 6 to theinletchamber 7, as illustrated in Fig. 7 of the drawings, the opening 23of the head will be entirely closed at that end in order to prevent thehead from conveying any of the material back from the outlet port to theinlet port. The adjustable end sections or members are provided withthreaded stems 27, engaging threaded sockets 28 of the body of thepiston or plunger. The end faces 29 of the adjustable end sections ormembers and the end faces 30 of the body of the piston are oppositelybeveled, the beveled faces diverging outwardly and being adapted tocompress and force outwardly packing 31, interposed between the saidbeveled faces. By this construction an air` tight connection between thepiston or plunger and the rotary head is produced and readilymaintained, and by placing a suiiicient amount of packing between theend sections or members and the body portion of the piston or plunger,the said end sections or members may be accurately positioned withrelation to the bearing surface of the outer casing. Should the endsections or members become 'worn or the packing become compressed, thelatter may be renewed and the adjustable end sections or membersarranged to lit properly against the interior of the casing. The endsections or members are provided with recesses 32, adapted to receive aspanner, or other tool for adjusting the said end sections or members.

The piston is reciprocated during the rotary movement of the head by anoscillatory crank element, preferably in the form of a horizontal crankshaft 33, provided at an intermediate point with a crank bend 34,arranged in a transverse slot 35 of the reciprocatory piston. The slot35 is provided with a suitable lining 36 to prevent wear of the piston,and the crank shaft operates in a cylindrical opening 37, intersectingthe piston receiving opening and constituting a lubricant chamber. rlheinner end 38 of the crank shaft is journaled in a bearing recess orsocket 39 of a solid horizontal journal or shaft 40 of the rotary head.The outer end of the crank shaft extends through a tubular journal 41,forming a continuation of the opening 37. The journals 40 and 41 arearranged in horizontally alined bearings 42 and 43 of the outer casing;the bearing 42 is equipped with a stuffing boX 44 having a suitablepacking, and the other bearing 43 is provided with a removable end wallor bonnet 45, a suitable packing 46 being interposed between the end orbonnet 45 and the end of the bearing. The tubular journal of 125 therotary head receives a bearing sleeve 46a, having a central openingthrough which the outer portion ofthe crank shaft passes. The bearingsleeve, which snugly fits the tubular journal, extends from the outerend thereof 130 gral with the adjacent into the chamber 37 andterminates adjacent to the crank bend, and it forms a support for thecrank shaft and prevents the same from springing in the operation of thepump. The outer portion of the crank shaft pierces the packing and theend wall or bonnet 45 and carries an upwardly extending actuating arm47, provided at its lower end with a hub 48 and adjustably secured tothe outer portion of the crank shaft by means of a clamping screw 49.rEhe upper o-r outer portion of the arm 47 is provided with alongitudinal slot 50, adjustably receiving a pivot 51, which connectsthe inner end of a pitman 52 to the arm. The outer cnd of the pitman 52is connected with a wrist pin 53 of a crank disk or wheel 54, mounted ona horizontal shaft 55, which is journaled in suitable bearings 56 of theouter casing. The bearings 56 are sectional, the sections beingpreferably formed intesections of the outer casing, but any othersuitable means may be employed for supporting the shaft 56. r'hehorizontal shaft 55 also carries a gear wheel 57, keyed or otherwisefixed to the shaft 55 and meshing with the gear wheel 58, mounted on theshaft or journal 40 of the rotary head.

A pulley 59, which is fixed to the shaft or journal 40, is in practiceconnected by a belt (not shown) withv a suitable engine or motor. Thegear wheel 58 is twice the diameter of the gear wheel 57, and t-he shaftand the crank disk or wheel 54 make two revolutions to each revolutionof the head l. At each revolution of the crank disk or wheel, theupwardly extending arm 47 is oscillated and swung inward from theposition shown in Fig. 6 to the position illustrated in Fig. 7 andoutward from the latter' position to the outer position illustrated inFig. 6. One half of a revolution of the crank disk or wheel carries thearm 47 from one of the said positions to the other. The reciprocatorypiston is moved upwardly when the arm 47 is swung inwardly, and whileits terminals are traveling across the inlet and outlet ports, therebythrough suction drawing in at the inlet port a quantity of materialoperated on and simultaneously expelling at the outlet port the chargeof material carried by the rotary head. The piston is reciprocated onlywhile the ends of the piston receiving opening or chamber is incommunication with the inlet and outlet chambers, and it remainsstationary while it is traveling` b'etween the said chambers. In Fig. 7of the drawings, the rotary head is shown as having received its charge`and as the arm 47 is traveling outward the crank bend 34 presses againstthe upper side wall of the slot of the piston and holds the pistonagainst the outer casing and etfectually prevents any of the materialcontained in the outlet chamber from being carried backward by therotary head. The piston is maintained stationary with relation to therotary head while the end, which is in contact with the outer casing istraveling from the outlet chamber to the inlet chamber, and the pistonbegins to reciprocate as soon as the transverse opening or chamber 23 isplaced in communication with the inlet and outlet chambers.

There is practically no work performed by the engine or motor while thepiston remains stationary with relation to the rotary head, and thisoccurs at each alternate quarter revolution of the rotary head. In orderto prevent the strain, the wear and tear and the other injury, whichwill result from the pump by suddenly relieving the engine or motor ofthe resistance of work at these periods and to store up the power duringsuch periods for use during the working periods of the engine or motor,when the piston is being reciprocated, the crank shaft is equipped witha weight 60, adjustably mounted on'a threaded arm 6l, extending from thehub 4S and arranged at right angles to the arm 47. The weight, which isinteriorly threaded to engage the threads of the arm, is adapted to berotated to move it inwardly or outwardly to vary its effect and toenable its effect to be increased as the column of liquid sustained bythe pump increases in length or height. The weight is lifted by theengine while the piston is relatively stationary and is travelingbetween the inlet and outlet ports, and it moves downwardly assistingthe engine while the piston is being reciprocated at the inlet andoutlet ports.

By this construction the operation of the pump is not only rendereduniform, but an engine or motor of half the power, which would otherwisebe required, is employed. Also the full power of the engine may beutilized and the operation of the pum-p rendered uniform by coupling twoor more of the pumps together and timing their operations, so that thepiston of one of the pumps will be reciprocating while the other isstationary with respect to the rotary head.

The upward and downward movements of the weight are cushioned by meansof a pair of cushioning devices 62 and 63, each consisting of acylinder, mounted on a suitable pivot 64 and receiving a cushioningspring 65 and a plunger 66, which carries a head at its inner end forengaging the cushioning spring. The outer end of the plunger of one ofthe cushioning devices is connected to the arm 47 by a pivot 67, and theplunger. of the other cushioning device is connected with the screw orthreaded arm 61 by a pivot 68. The weight is cushioned at Ithe end ofeach of its movements and is prevented from jarring or otherwiseinjuring the pump. Various other forms of cushioningl means may,however, be employed for cushioning the weight at the ends of the upwardand downward movements thereof. The gear wheel 58 also meshes with asmaller gear 69, mounted on a horizontal shaft 70, journaled in suitablebearings 7l and located at the opposite side of the pump from that `atwhich the shaft 55 is arranged. The bearings 7l are constructed similarto the bearings 56, and the shaft carries a balance or fly wheel 72 forrendering the operation of the pump steady and uniform.

The chamber formed by the crank shaft receiving opening 37 is adapted toreceive a lubricant, and a suitable oil passage 73 communicates with thesaid chamber and preferably extends through the end plate or bonnet 45and the bearing sleeve 46a to enable oil to be introduced into thelubricant chamber. The lubricant chamber is adapted to containsufficient oil to lubricate the inner end of the crank shaft and alsothe reciprocatory piston or plunger. As such parts operate in oil thefriction is reduced to a minimum. y
